Hi All,

My 2010 Audi 2.0T is in need of carbon buildup removal in the near future and the local German Auto Repair house quoted me $690 to walnut blast the intake valves.

They are using a setup they put together that consists of a blaster and vacuum. I have seen some YouTube videos that make this look pretty doable for the shade tree mechanic.

Any advice, warnings, or "Don't be an idiot, pay the professionals" comments are appreciated.

Thanks,

Greg

You can buy adapters and tools to do it... or go full backyard:

I used a plastic scraper, small wire brush some petrol and some old toothbrushes. It doesn't have to be immaculate, just the chunks gone - but you can get it pretty good.

Yeah well is carbon cleaning a listed requirement of a conformity certificate application, service book or RTFB procedure?

What's the miles on this car and have you considered submitting such a bill to the OEM for useful life warranty?

Do you have an MIL as a result of said carbon?

Ever read the JPPSG?

Post an auto-scan if you like & so we can see what it's made of?
